在使用時，應避免在易爆環境下使用，例如使用環境中存在易燃液體或氣體，需要相關鏡頭和導線的防護。
When in use, it shall be avoided to use in explosive environment, such as flammable liquid or gas in the use environment, which requires the protection of relevant lenses and wires.
遇到檢測中有高壓電線等帶電物體時，操作者應該先對斷電，否則手持式工業視頻內窺鏡暴露在外面的金屬部位導電，導致使用者被電擊，也容易造成設備的損壞。
In case of live objects such as high-voltage wires in the detection, the operator should cut off the power first, otherwise the exposed metal part of the handheld industrial video endoscope will conduct electricity, resulting in electric shock to the user and damage to the equipment.
盡量不要在溫度過高的熱源周圍使用，當然具備耐高溫的也需要在規定的溫度范圍內操作，使用時必須保持使用區域的清潔及照明亮度。
Try not to use it around the heat source with too high temperature. Of course, those with high temperature resistance also need to operate within the specified temperature range. When using, the cleanliness and lighting brightness of the use area must be maintained.
在使用的過程中，不要把插入管過度伸張和彎曲，無論在什么時候都應保持在插入管的彈性范圍以內的基礎平衡。
During use, do not stretch and bend the insertion tube excessively, and keep the basic balance within the elastic range of the insertion tube at any time.

在使用時，應當盡量小心，手持力度應該控制，緩緩移動，以免力度過大撞壞損壞儀器。
When using, you should be as careful as possible. The hand holding force should be controlled and move slowly to avoid damaging the instrument due to excessive force.
就是手持式工業視頻內窺鏡的維護保養問題了，在使用完畢，我們應將探頭及機身用干布擦拭干凈，以免殘留物日積月累腐蝕儀器。
The problem is the maintenance of handheld industrial video endoscope. After use, we should wipe the probe and body with a dry cloth to prevent the accumulation of residues from corroding the instrument over time.
擦拭完畢后，用專用的存放收納起來，再進行存放，以便下次取用，這里值得提醒的是存放地點切勿潮濕。
After wiping, store it in a special storage for the next time. It is worth reminding that the storage place should not be wet.
當手持式工業視頻內窺鏡需要維修時應聯系經銷商或廠家，交由專業的維修人員檢測。非專業人士不要拆卸及嘗試修理，以免破壞儀器。
When the hand-held industrial video endoscope needs maintenance, contact the dealer or manufacturer and submit it to professional maintenance personnel for inspection. Non professionals are not allowed to disassemble and try to repair, so as not to damage the instrument.
